All of the above is speculation and gossip regurgitated in the media and traced back to the usual unsubstantiated 'anonymous sources'. ISI officials would not be using any sort of cell phones traceable back to the agency (even the TTP is smart enough to use the equivalent of 'burner SIMS') nor would high ranking ISI officials have any interest in direct communication with any such attackers/facilitators.
Carlotta Gall claimed that her allegations of a 'secret OBL cell in the ISI' was corroborated by some 'anonymous sources in the US Administration/military/intelligence', and in a piece that was largely a counter-argument to Gall's allegations, Peter Bergen (on CNN) quoted some other anonymous high ranking US Administration/military/intelligence officials as claiming that they had no evidence of any kind that the ISI was aware of OBL's location.
So unless the claims you regurgitated above can be credible substantiated, they are nothing more than Gall's ludicrous and irresponsible claim of a 'secret OBL cell in the ISI' based on the usual 'anonymous sources'. Gall, much like Christine Fair, has reduced herself to little more than an anti-Pakistan hack by propagating half-baked and poorly sourced and poorly corroborated fantasies and conspiracy theories, perhaps out of anger at her poor treatment when covering a story in Balochistan and eventually being kicked out of Pakistan.
It is not just Gall's reporting. There is a wealth of other sourcing available. The most relied on is the NYT article that I have referred to here.
Pakistanis Aided Attack in Kabul, U.S. Officials Say
By
MARK MAZZETTI and
ERIC SCHMITT
Published: August 1, 2008
WASHINGTON — American intelligence agencies have concluded that members of
Pakistan’s powerful spy service helped plan the deadly July 7 bombing of
India’s embassy in Kabul,
Afghanistan, according to United States government officials.
The conclusion was based on intercepted communications between Pakistani intelligence officers and militants who carried out the attack, the officials said, providing the clearest evidence to date that Pakistani intelligence officers are actively undermining American efforts to combat militants in the region.
....
The New York Times reported this week that a top
Central Intelligence Agency official traveled to Pakistan this month to confront senior Pakistani officials with information about support provided by members of the ISI to militant groups. It had not been known that American intelligence agencies concluded that elements of Pakistani intelligence provided direct support for the attack in Kabul.
American officials said that the communications were intercepted before the July 7 bombing, and that the C.I.A. emissary, Stephen R. Kappes, the agency’s deputy director, had been ordered to Islamabad, Pakistan’s capital, even before the attack. The intercepts were not detailed enough to warn of any specific attack.
The government officials were guarded in describing the new evidence and would not say specifically what kind of assistance the ISI officers provided to the militants.
They said that the ISI officers had not been renegades, indicating that their actions might have been authorized by superiors.
“It confirmed some suspicions that I think were widely held,” one State Department official with knowledge of Afghanistan issues said of the intercepted communications. “It was sort of this ‘aha’ moment. There was a sense that there was finally direct proof.”
The information linking the ISI to the bombing of the Indian Embassy was described in interviews by several American officials with knowledge of the intelligence. Some of the officials expressed anger that elements of Pakistan’s government seemed to be directly aiding violence in Afghanistan that had included attacks on American troops.
Some American officials have begun to suggest that Pakistan is no longer a fully reliable American partner and to advocate some unilateral American action against militants based in the tribal areas.
The ISI has long maintained ties to militant groups in the tribal areas, in part to court allies it can use to contain Afghanistan’s power.

Is Pakistan America’s Ally?
By Dexter Filkins
In testimony before the Senate Thursday, Admiral Mike Mullen, the Chairman of the Joint Chiefs of Staff, said that agents of Pakistan’s spy agency—Inter-services Intelligence, or I.S.I.—provided support for last week’s attack on the American Embassy in Kabul. (American embassy but the logic of ISI's support to terrorism remains) That is stunning news. It may turn out to be the event that compels President Obama and his advisors to finally force significant changes in America’s alliance—the word is used lightly here—with Pakistan’s military and civilian leaders. As I suggested
in a recent piece on Pakistan, we should not be surprised by the I.S.I.’s blatant venality, or by its willingness to act so aggressively against American interests, despite the billions of dollars Pakistan receives each year in aid.
The United States embassy was attacked on September 13th by a group of insurgents who American officials say came from the Haqqani network, an especially lethal group that is allied with the Taliban. The assault was extraordinarily brazen: the American Embassy is in downtown Kabul, and is adjacent to the headquarters for the American military and its NATO allies. Sixteen people were killed, including eleven civilians—six of them children. (The Embassy itself was not breached.) The Embassy attack was one in a series of spectacular operations, which have included assassinations and suicide bombings, that have contributed to a growing sense of demoralization among the Afghans and their American sponsors.
If the I.S.I. was indeed involved in the planning or direction of the Embassy attack, it would constitute the most dramatic evidence yet that the Pakistani military and security agencies are actively trying to subvert the American-led project in Afghanistan. But it would not be the first such evidence: American and Western officials have been saying for years that the I.S.I. actively supports Taliban and Haqqani insurgents who are killing American troops.
In 2008, according to American officials, I.S.I. agents helped facilitate the bombing of the Indian Embassy in Kabul, which killed fifty-four people

US allegations of ISI links to Haqqani attacks stretch back to July 2008, when the CIA deputy director, Stephen Kappes, flew to Islamabad with intercept evidence that linked the ISI to an attack on the Indian embassy in Kabul.
US bomb warning to Pakistan ignored | World news | The Guardian
,,,,,About the car-laden explosives that went off at the Indian Embassy in Kabul that killed 58 people and injured 141, Mike Waltz, who worked in the US vice president's office while George Bush was still president, said: "Through information and a series of events (not to mention preceding intelligence intercepts), it became pretty clear that the Pakistanis were behind the (Jalaluddin) Haqqani network, which was behind the bombing."
He then damningly concluded
: "The question was how high in the Pakistani state this went. And the answer was pretty high."

2. Polish intelligence warns of attack on Indian embassy: A July 1, 2008, threat report issued by Polish intelligence in Kabul warns of an attack on the Indian embassy, which was carried out a week later.
The
report reads: “INS [insurgents] are planning to divide into two groups: first will attack Indian embassy building, whilst the second group will engage security posts in front of MOI [the Afghan Ministry of the Interior], IOT [in order to] give possibility to escape attackers from the first group…The main goal of this operation is to show TB’s [Taliban's] ability to carry out attack on every object in Kabul.”
Then-U.S. President George Bush and CIA Deputy Director Stephen Kappes confronted the Pakistani government and ISI directorate with evidence that ISI elements aided militants in the attack.
