iPhone 3.0 beta - what effects does it have on the iPhone?
<p>I am currently developing applications on the 2.2.1 sdk, and considering to upgrading my iphone to sdk 3.0. Can my phone still be used to run old version programs (2.1, 2.2 etc), call, send sms and so on? Or will it be restricted to only be used to test 3.0 developed programs?
Thanks, Hans Espen</p>
