Can I upgrade my iphone 4 baseband to 06.15.00?

[IndiansLoveME]

I got a used iphone 4 but accidentally update the ios to 5.0.1 and now I can't unlock because of the baseband 04.11.08.

I know that it's possible to unlock the ipad baseband 06.15.00.

This baseband can be installed in the iphone 4? I already use it in my old iPhone 3G.

And I know that I will probably lose GPS functions, but I don't use it, so I rather lose GPS than wait months until a possible unlock is available.

You can't update the iPhone 4 BaseBand to 6.15.00, that's only for the 3G and 3GS.

You have three options:

1. Use it on AT&T.
2. Wait for an unlock solution.
3. Use it with Straight Talk. Straight Talk uses AT&T's network and costs $45 a month for unlimited talk, text, and web.

Werd I'm not sure if its even possible to load it on the phone but if it is you'll brick it...
