I'm in need of some help here. I had a previously unlocked iPhone using iphonesimfree and decided to try and install the following to get 3rd party apps on my iPhone - http://lifehacker.com/software/hack...+party-applications-on-your-iphone-295985.php Suffice it to say that it didn't work and now my iPhone won't reset and has a yellow triangle that says to connect to iTunes. I tried turning it off and also holding the home button and the off button and it only reset with the yellow triangle. I'm obviously worried that I've screwed my phone up. Can anyone suggest how I can get my phone back to working order again? I'm desperate to figure this one out! Thanks in advance!
