Apple's cat-and-mouse game with iPhone hackers seems increasingly one-sided. The last firmware update (1.1.4) was hacked within days, and free cracking applications Independence and Ziphone have made unlocking the iPhone from 02 (UK) or AT&T (US) easier than ever before - assuming you're happy to invalidate your warranty and risk your phone being turned into a useless brick by a future update.
To make matters worse for Apple's official network partners, it seems that the forthcoming upgrade to iPhone version 2.0 has been hacked. The version 2.0 software update incorporates Microsoft ActiveSync push email and the ability to install officially sanctioned third-party apps such as and Spore (yey!) Supermonkeyball ( double yey!) .
Cynics are suggesting that Apple is turning a blind eye to hackers because it's desperate to reach its target of 10m sales by the end of 2008 - even if some of those iPhones aren't being used on the official networks.
Time will tell whether pressure from O2 in the UK and AT&T in the US will force Apple to close its software again - and potentially brick another batch of hacked iPhones.
In the meantime, we can be pretty sure that a lot of effort is going into producing software for the iPhone - with over 100,000 copies of the iPhone SDK were downloaded, it seems that there's one software developer for every 50 iPhone users...
