iphone no longer switching to 3G after jailbreak

[tirexstorm]

I jailbroke my 2.0 3G phone last night. Everything seems to be working except it is no longer automatically switching to 3G.

If I restart the phone, or put in in airplane more, then turn plane mode off, it will find the 3G network no problem. However, when I lose a 3G signal and my phone switches to edge, it never goes back to 3G automatically. I have to restart or do the airplane mode off-on trick again. Any suggestions?

On an unrelated note, if I want to update to 2.0.1, can I just let itunes do the update? I realize that I will lose the jailbreak apps, just want to make sure that plugging my phone in and hitting "update" won't cause any sort of problems. If I have to do a restore first, how do i do it?

Thanks!

You should try and re-jailbreak.

On the update note, you can just hit "restore" in iTunes and it will take it to a factory 2.0.1 condition. I wouldn't "update" from a jailbroken 2.0 to 2.0.1 though

Just curious why you say this. If the firmware is being replaced, what difference does it make what's on there currently?

AFAIK an "update" does just that. It updates the current firmware, not fully replacing it. If you are jailbroken you will at best lose the jailbreak, and at worst have to do a restore anyways due to permissions/buggy software/overwritten jailbreak files/etc.
