I haven't upgraded yet from 2.2.1 and I am wondering whether it is worth it to upgrade now or wait for 3.1. I have a non-jailbroken 1st Gen Touch and I am concerned about the problems others have had with wifi reception being worse after the upgrade. I'd like to hear how others with a 1st Gen Touch feel about the upgrade. Worth it or not? Problems they have had, etc. Thanks.
