Yea, its an Apple thing alright. However, I've found that by setting the brightness all the way down, you will still get good power life. However, the GPS should still work if it autosleeps or you ONLY press the power button at the top. If you are losing GPS in either of these cases, something is amiss.

Hmm… next time I'm out running or biking I may have to check this out. However, there are plenty of other dataloggers I would recommend that you can use now. Would be interesting to see how others would work for you. check these posts out and give one a try. http://www.perivision.net/wordpress/?cat=67 'Path Tracker' is my default app of choice.

I was also wandering if the full version would also nag every time about the EULA and had to wait for it so long before use?

I agree, putting one's iphone on a bike mount is nuts. Now if it was an ipod touch, then perhaps. The safest place to keep your phone is in the seat pouch. However, make sure you have the bottom of the phone towards the rear of the seat. That is where the antenna is, and you need to make sure the antenna has the best view of the sky as possible. I normally keep mine in the back of my biking shirt.
