What is your opinion on the iPhone? vs HTC HD2 vs Sony Ericsson Satio?

The satio has a lot of software probs and is prone to stalling and freezing. Plus the app store is practically non existent, so it's difficult, if not impossible to add new apps. The best thing about the satio is the 12mp camera. The HTC is a good alternative to the iphone, and is cheaper which appeals to many. However, personally i think the iphone is a great phone. Despite the fact the camera is only a 3.2 mp without a flash, it actually takes great photos. And if you want the flash, you can download the flash app from the app store, which improves photos considerably.. The iphone will certainly be relevant til the new iphone comes out at least, as the app store is ever increasing.
