This is one of the most useful things ever. The idea is brilliant and i predict a long and bright future. If Apple wont find anything that will violate their TOS or whatever, iBetaTest will change the game dramatically.
iBetaTest is an on-line service designed to bridge the gap between iPhone application developers and beta testers. It’s here to provide iPhone developers with a community dedicated to quality control, and at the same time provide Beta Testers with what they crave the most: exclusive access / first look to the apps not yet seen .
