I just installed the latest iCosta 1.0.4 for my 1.0.2 iphone from here(1.0.x). If yours is 1.1.x, please visit 1.1.2 or 1.1.1.
From the release notes i learn iCosta can now work with LumaQQ iPhone edition as well. I’m not a QQ user. If you are and happens to own an iphone, why not give it a try?
The first is about iphone hardware unlock. It’s a more easier hardware unlock than GeoHot’s version, even if it’s actually based on the latter.
The ‘big’ improvement is no soldering needed. Instead, it uses two noodles.
The second is Apollo IM, the iPhone Native Instant Messenger Application now in early beta. However, for people in China, the most-used IMs are QQ and MSN Messenger. Hopefully, Apollo would add the support to at least MSN Messenger soon.
Anyway, the US iphone owners, esp. the regular AT&T registers, may give Apollo a try.
