I have an iPhone 4 at baseband 01.59.00 that is stuck in recovery mode. I cannot get it to exit with RecBoot or TinyUmbrella. I tried using PwnageTool to make a custom 4.1 IPSW, but when I try to restore from it, iTunes says that "this device isn't eligible for the requested build."

A different method involves using TinyUmbrella, but it always gets stuck on "TSS Accepting connections"

I am sure it might have been answered before, but after using Ultrasn0w, my iPhone 3G keeps dropping the wifi connection.

I decided to upgrade my iPhone 2G (unlocked on T-Mobile with the 3.0 software) to the iPhone 3G.

I found it on craigslist for $225. The iPhone 3G I am buying was originally purchased in December 2008, so the baseband will most likely be past 02.28.

When I first buy the phone:

1. Yellowsnow will not work, so what can I do with my phone until Ultrasnow is released?

2. When Ultrasnow is released, do I use Redsnow jailbreak my phone, and then use Ultrasnow downloaded from Cydia to unlock?

After I have unlocked it with Ultrasnow on 3.0:

3. I know that I have to disable 3G, but can I get GPS to work on the phone? I read something about adding T-zones for $5.99 will work, is this correct?

4. Will MMS work on the iPhone 3G after iPhone OS 3.01 comes out?

Answering these questions will help a lot, thanks.

I have a 2G iPhone that I unlocked before using PwnageTool, today I tried to upgrade to 3.0 and everything seemed to work fine. However, I keep getting a "Cannot connect to iTunes" error. Any ideas?

Is there any chance features AT&T doesn't support yet (MMS, tethering) will work on T-Mobile USA?

But when exactly does quickpwn for 3.0 come out? Tomorrow? Before Friday? Or later?
