I have an iPhone 3Gs and just updated to the latest 3.1.2 jailbreak. I'm still on the old BB (04.26?) I use AT&T so I don't totally need to unlock, but now when I connect my phone to iTunes it asks to update my BB. Are there any issues with the unlock or updating the BB with iTunes? It would be nice to have the carrier logo again. My phone works great and I have read previously about issues after unlocking. Thanks!
