Sup fellow iOS nerds? I figured we need a thread to post about cool stuff that goes free (or super cheap) so we can add to the hundreds and thousands of other apps we have. To start it off, on June 26, 2011, Death Race (Universal) is free!
iFile-upload/download files to your iphone without having to physically connect to a computer (you can use wifi) (free for personal use) Backgrounder - you control what apps are allowed to be ran in the background and when (free) Multiflow - in conjunction with backgrounder it's the best multi tasking interface out there ($5) SBSettings - access your settings easily and quicker (free) Covert - add private browsing to safari Camera buttons - allows you to use/activate the camera by pressing or holding different buttons ($.99) Street fighter - one of the best games on the iphone! (currently $.99!)
If your phone is jb then pick up snes9x, it's based on the pc snes emulator by the same name and it's free! (it's also available for android).
