I downloaded the official SDK from apple already and I plan to start working with it in the near future. ( I just downloaded the SDK without paying the $99 fee to use the AppStore) but......... I have seen quite a few articles about how the open source toolchain ("unofficial" SDK) can compile for the 2.0 FW (am I wrong?) and that using apple's SDK can be a hassle due to certain restrictions in the development process. I hear that there are a few important frameworks that are impossible to communicate with. (unless you plan to distribute thru the AppStore in which case you have to use apple's official SDK. My question is this: 1-Should I delete apple's SDK and instead build the open source toolchain that supposedly will compile for 2.0?? 2-Is it true about the restrictions apple places on their SDK? 3-Which is a better toolchain for someone like me who develops really only as a hobby and doesn't plan on releasing anything in the AppStore (unless I make something worthwhile which is doubtful considering I'm still in the learning process)???
