I just bought a 2008 version T-Mobile Sidekick. It doesn’t seem to allow me to use the mp3 songs that I have on my memory card as ringtones. Is there any websites where I can download ringtones, backgrounds, games, screensavers and such for free that will work on my phone?

So my parents of thinking of getting me a new phone for Christmas(Due to the Sidekick outage and my phone wont work properly). I really cant choose between the Cliq or the Behold II.

Motorola Cliq:Pros:Physical keyboard, sleek design, and the fact that its an android, also the 5 MP camera.Cons:Theres no flash, i hear the battery dies fast.

Samsung Behold II:Pros:Android based, its a samsung phone, i hear it has an excellent battery, it has flash for the camera and its 5 MP.Cons:No physical keyboard, its mixed with the touch wiz, and that its super laggy.
So can anyone else tell me about these two phones and which one would be better?
Also im a big texter, call a lot, takes a ton of pics, and listens to music all the time.
P.S: can you customize the wallpaper on them and have one of your mp3 songs as a ringtone?
Thanks

Like, is there a website I can upload my MP3 songs to then make a free ringtone? And then how can I get it on the phone?
