Hi- I'm planning to upgrade my 3GS to iOS5 today but don't want to risk losing any data. From apps to emails to 2 years worth of text messages (keeping for both professional and sentimental reasons), I'll leave it as it is if it means losing all that info.
If/when people start making updates I'd love to hear how it went and if you notice any loss of data, if all your settings needed to be reconfigured, etc...
Thanks!
Then just do a manual backup on iTunes real quick. That way it saves all your texts and photos and important/sentimental information.
That's what I always do, since I am the same way with my texts.
Never had a problem updating over the air from iOS 5 beta 3, 4, 5, or 7
EDIT: Although I did have a problem from beta 4 to beta 5 and up where they changed how many texts your phone could hold.
For some time I was unable to receive texts because I had too many and it wouldn't delete the oldest ones in the threads on it's own.
So I had to go in and delete a huge message thread from an ex-gf and then all the texts I was missing came flooding in.
So I don't know if they have fixed that problem yet, but apparently I was the first to run into it on here, since at the time no one knew of that problem existing.
