i have a question that needs a serious answer! i am going to europe for about 15 days and i am currently running iphone os 3.0 beta 5 on my iphone. i leave the country june 4th. Hopefully they will have a new beta release by then but anyways should i take my macbook just incase my beta expires and my phone becomes useless for a few days? or should i just take the chance? i will mainly be using it to play games watch movies and listen to music thats all bc i am not taking my phone out of airplane mode! How long do beta's last before they expire? thank you!
