Ok so i'm a bit behind, have had an iphone 3g which i've jailbroken unlocked with ultrasnow i think it was... but in any case an app through cydia. 1) I know as of a couple months ago the only way to unlock a 4s was with teh gevey unlock. Is this still the case? 2)If I buy a gevey unlock thing, does it only work once/do you have to keep it in the phone? If i was going to unlock 2 phones would I have to buy 2 gevey unlocks? 3)Anyone have experience with these problems of sms/mms on 5.1.1? Is there any fix for this yet? Going to buy an iphone off ebay trying to determine what ios would be ok. If there 4) if no fix yet, is it possibly to downgrade 5.1.1 to one that doesnt have these problems?
