How to fix a weird iPhone 4S auto-correct issue?

Okay, so about last week, I noticed that whenever I misspell "you" on my iPhone, auto-correct changes it to "ÿøù". I don't know why it does this. Also, when I tap on the word to look for other suggestions, the proper "you" spelling isn't even listed. How do I get rid of this problem?

My iPhone 4 continuously lags after jail breaking, what do I do?

I have an iPhone 4 running iOS 5.1.1. I used absinthe 2.0.4 to do the jailbreak. After the jailbreak I soon noticed lagging in my system as well as apps taking anywhere for 30 seconds to 3 or 4 minutes to successfully opening without fail. I managed to delete Cydia and it still lags. I've factory reset it and it still lags, what do I do?

Is the iPhone 3GS still worth it?

Using a Wildfire S here, driving me mad. Problems with storage and lag are making me consider buying an iPhone 3GS second-hand off of eBay.

But as the title says, is it worth switching? I don't mind sacrificing the 5MP camera in favor of the 3MP one as I rarely use the camera on my phone.

Added (1). Obviously, I can only afford a 3GS.
