Just a few weeks after its first update, the Samsung Instinct has received its second major firmware update.

They’ve chosen to roll out this update in an interesting fashion. Rather than pushing out one big update for the phone, they’re pushing out a series of updates for each affected feature. The updates include:

• Picture mail (fixed some errors)
• Browser (rendering optimizations)
• Sprint TV/Radio
• Sprint Navigation (better battery usage)
• Sprint E-mail
• Sprint Music Store
• Visual Voicemail

It sounds like a nice collection of updates for an already popular phone.

Best Buy is expected to announce an agreement with Apple to start selling iPhone 3Gs in 986 stores starting on September 7th.

Best Buy has just completed a major upgrade of their “Best Buy Mobile” departments, which may have been a part of this deal. Best Buy already sells some other high-end phones, such as the Samsung Instinct, so it makes sense that Apple would want to put their own device out there as well.

The official announcement is expected as early as tomorrow.
