Someone on these forums posted a fix for the lag. He says that it worked for him... but i'd like to know if it works for anyone esle? Is there anyone willing to give this a try? Honestly I have so much stuff on my phone i'm really not looking forward to trying this out. I'll do it though, if it actually works. Here is what he claims works: Well, an hour and a proper restore (without restoring from backup) later, everything seems fine. No more keyboard lag in SMS, Mail, or contacts. Id recommend it for anyone having problems. 1.) Delete the backups (in itunes preferences > iphone) 2.) Restore the iphone to 2.0.1, without using the back-up file (because you've already deleted it) Is the lag fixed? Please post and let us know, thanks. Please try it out, and if you can... post like every 4 hours or so and let us know how it's been working throughout the day.
