Porting Android to iPhone 4, 3GS and iPad looks imminent. According to the interview with the guy behind project to get Android running on the above mentioned devices, that the process has accelerated drastically.
NICK: Work on the A4 port started late last year, but progress was slow due to there being a lack of skilled developers on the team to work on it. In the recent few weeks, the port has accelerated drastically. The 3GS port was started a couple of months back but lessons learned from the A4 port helped to bring it inline quickly. Due to the nature of the project, it is completely impossible to estimate just how long these things take. This is mainly due to the sheer volume of reverse engineering that has to be done, but we are working with largely undocumented and uncommon hardware so it comes with the territory.Actually the developer behind iDroid project didn't give an estimated to arrival but they became very close to release their project. As usual I will let you informed with each update, stay tuned.
