Apple announced that come the end of February (about 2 weeks away), a SDK (software developer kit) would be available for people to create software for the iPhone (natively- not online).
As someone that has an iPhone and really likes it – there are times that the ATT system leaves something to be desired and I do not get a signal (or I’m in the subway etc.) and would like to remember something etc…
An app on the iPhone could fill that gap. Right now people are saying that iPhone 1.1.4 will actually be iPhone 2.0 and arrive “very soon”. I’m looking forward to it!
