How to reset everything on your iphone 3G?

I just recently got a new iphone, and i plugged it into the computer, and it was immediately "restored" to my parents phone, who also has an iphone.

Does the iPhone camera make your body look different than what it is?

So everytime I look in any of my bathroom mirrors (which are big mirrors btw), my body looks much longer and less squooshed laterally than what the iPhone makes out. My face even looks more proportional in the mirror than the iPhone's camera as well. This is really hurting my self esteem and I'd like to know if the iPhone is more accurate?

Having trouble creating custom ringtone for my iphone?

Once I've created an AAC version of a shortened song and copy and paste it to my desktop, I just get the name of the song displayed, not ".m4a".So even if I do add ".m4r" to the end everything after that doesn't work. Once adding "m4r" after right clicking it the file is still an m4a, it will just now read "Song name.m4r.m4a". Can someone please help? My iphone is an iphone 4.

How to remove sticky stains on wooden dining table?

My mom is really upset about this so I just want to get a solution soon lol.

We have this new wooden dining table. Instead of using a normal table cover she used this plastic see through table cover. After that was used for a month or two she removed it and it left sticky stains on the table. Over time I guess the plastic kind of got stuck on the table. Think of a screen protector on an iPhone.

Anyways she rubbed it with warm water and stuff but the sticky residue won't go away.
What can we do and sue to remove these sticky stains without ruining the table?
