I can understand not JB for personal reasons but to make some of the wildly false statements for reasons as I've seen here is a joke. "I don't have the time"..... LoL, takes 3 minutes to JB a phone.... If you don't have 3 minutes than you have more issues in your life than JB. As far as the threads that pop up r/t apple updates and JB.... anyone that has half a brain in their head know what to do U(or not do) when apple comes out with an update r/t JB. Those that start thread after thread about it are the same one's that start the threads about one of their bottom speakers not working. JB does nothing to mess with the "established specs", any one that says it does either has no clue or is liar. JB does nothing but give you the ability to put "non apple aproved" apps on your phone, it's what you put on your phone that may "slow it down." I had a very moded iPhone next to a stock iPhone and did a video side by side..... the JB i was a bit slower opening some apps.... by a bit I mean 0.5 seconds slower. If half a second is to long to wait refer to my statement above r/t the 3 minute JB process.
To jailbreak or not to jailbreak, that IS the question.... however don't let the fear of the unknown keep you from trying. Don't let the wild accusations some have given for a reason not to JB keep you from trying. It takes 3 minutes, give it a try and mess around. Fresh locked apple firmware is just a restore away.
Jail broken sense the days it took 45 minutes and COULD brick your phone..... Jail broken 3gs sitting by my side. Jail break today, jail break tmr, jail broken forever baby!
