Since I'm somewhat new to the whole jailbreak thing. Will previous apps like pdanet, intelliscreen, cycorder, and iphonebrowser work with 2.2.1(jailbroken)?
I am on an Iphone 2g and I use Jailbreak but only 1 application (SBSettings) so Jailbreak is not important for me. I just need to unlock the Iphone to use on any SIM card in the world. Currently I am on 2.2, if I upgrade via Itunes with the official method to 2.2.1 it will be okay right? More importantly, can I Jailbreak at a later date? I don't want to lose all my highscores on my apps so I don't feel like restoring from scratch.
NOTE: I only used it to enable emoji, then I backed up my phone, then I restored it by putting it in DFU mode. It was only jailbroken for about ten minutes so I could enable emoji.
