Uploading to i560

So I just bought a i560.. switched over from a Sprint account to Nextel. Well first thing I of course am trying to do is get some pictures on there for wallpapers. I already found out the screen size is 130 by 130.. I went ahead and made a image to the right size and all. Well I tried using one uploader, coolservice.com, my browser on the phone just refused to go to that site. I tried another, http://rumkin.com/tools/sprint/index.php, it worked to where I enter the jump code but it just says data too large or something. The image is like 12KB.

Is this a problem with my phone or what? Did I manage to scew up in picking Nextel and they just dont like any of that? I can make my own midis and jpgs, Id rather not pay for ones I dont even like as much, Id like to just upload them from my computer to my phone.

Try a data cable and the appropriate software, like P2KMan or MPT, and uploading pics and/or ringtones becomes a snap...

Eh.. Im going to stop by the store again to see about the cable. Though I have free internet, I would have just liked to send it that way... isnt there any other way?

yup.. Every store I went to was sold out. So um.. any other way? Can I just host a JPG myself and send the link to my phone? Ive also been manually entering these addresses in my phone, its a pain.

What.. no one has anything? Wow..

So I finally got ahold of a USB Data Cable.. I installed MPT and it wont even install my phone, says it can not find it. Its not even in a list when it asks me to manually select it.. what the hell. Can I get some help using it?
