The BlackBerry may be handed one of its more significant losses as insiders said today that JPMorgan and UBS are working to allow Android and iPhone hardware for their workers.

Under the proposed final plan, staff would have to pay for the phones themselves, unlike the BlackBerry, but could use it for both personal and company work.
