I'm less than two weeks away from starting my Springer -> Damascus trip. To say I'm antsy is an understatement. There are a few things up in the air but I have a good idea where the answers lie.
One thing I'm still undecided about is whether to upgrade my iPhone 3GS to the 5.whatever OS. I want to download a trail map app that requires it. I have regular maps and was not going to rely on the app, I just wanted to compare and see if in the future I could do without.
Any input on upgrading or not that's specific to iPhone needs/uses on the trail? Does the latest OS really drain the battery as much as people moaned about?
