iPhone "Other" 3.3GB Capacity

I know that this question has been asked about seven billion times, but none of the solutions have worked for me. I have a white iPhone 4, 16GB, brand new January 2nd, 2012 (replacement from the apple store on a 3 month old iPhone) There is 6.6GB of Music, 0.19GB of photos, 1.51GB of Apps and 3.3GB of Other.

I have

- Restored my phone from back up

- Unchecked sync music, and then sync'd my music back on (and with books, photos, calenders, contacts, etc)

- deleted all my photos

- deleted all my music

- deleted all my apps

- plugged my phone into itunes and dragged a song not on the iPhone to it.

- looked in my storage to see what apps were using a lot of space

- emptied my browser history on safari

- deleted all bookmarks on safari

- emptied my trash in my email

- deleted my email account from my phone

- turned of iCloud

- had nothing on my phone (except text messages & contacts) and my other was at 3.2GB versus 3.3 with everything on it.

What the **** is going on? I'm getting increasingly frustrated with apple and my phone. I'm deleting photos/music/etc to make room for OTHER now which is ridiculous. I'm not willing to do a restore to factory settings, nor should that be the only option. Has anybody been in this situation and found something that worked for them? 3.3GB is a lot of space to lose when I already have only 16GB for my phone.
