    Well, every once in a while i tend to update my iPhone when it is totally safe to do so. I am aware of how to save your baseband using TU. I just have one question. When i hit shift+restore and choose the 4.2.1 firmware for my iphone (running TSS server ofcourse) Should i choose to set up a new device or choose it from a backup. I am hoping to keep all my applications and contacts. I am currently unlocked using T-mobile. I have a couple of cydia apps and other installed applications, songs, videos. Will i lose all my data if i hit "restore as a new device" (i am guessing yes). And is it okay if i just choose this from a backup? I know once i update to 4.2.1 i will be able to jailbreak using Green Pois0n, but i want to be able to update to 4.2.1 while keeping everything intact. possible?

    I would just use PwnageTool. It removes any possibility of mistakes that turn the phone into an iPod. Then you can just restore your backup, which works but can cause weird problems sometimes.

    I thought pwnagetool is only for macs or iphone 3gs and lower. Hmmm.

    yes pwnagetool is only for mac. and if you shift restore you will lose your unlock as tinyumbrella does not retain your baseband anymore. so try to find something with a mac to use pwnagetool or find a pwnagetool firmware online
