I am new to Jailbreaking and have been searching this forum for preparation. I have been reluctant to proceed in the past, but really want the SBSettings utility. This feature is totally awesome. However, I may consider the following: SMS Quickreply Backgrounder Customize SMS tones Getting rid of that darn "This accessory is not made to work with iPhone" message (I know it's not; now leave me alone and stop asking me!!!) I am running Windows and using the latest firmware 3.1.2 on a iPhone 3g with an expired warranty. I have no need to unlock. I want to keep everything running as smoothly as it does now. It seems that my best option is Blackra1n, as Pwnage is only for Mac. Correct? Is there a potential for problems syncing afterwords? Are there any battery life issues? By limiting my hacks to those listed, will I see any effect on overall performance? Does jailbreaking result in more frequent crashes or freezes? (currently, I rarely have any). Thanks in advance!
