Well i jail broke my iphone 3GS the day i got it , which was the day it came out in july i believe of last year. i never did the MMS upgrade because i new it would unjailbreak my phone, so i've been hobbling along with Swirly MMS to send pictures. For a while i didnt want to upgrade bceause the Cydia forums on my iphone said they havent had a crack yet for the new 3.1. So my question is, is it finally safe to plug my phone into itunes and let it upgrade it? i know it will probably temporarily unbreak the phone untill I do a simple makeitra1n jailbreak. Is there an easy way like that to do it these days? I have a SHSH on file with Cydia with my phone. Or is there not a jailbreak for the 3.1.2 software? If there is, please give me details on what to do to get my jailbreak back up and running after OS upgrade. Thanks
