Basic Help Please

[Brian52682]

Hello, I am new to this forum .. I just purchased the Motorola Q and it is my first smart pc phone. The guy at the store told me I can watch tv (dont know how) and can listen to sirius radio (also dont know how).. I am going to browse the forum and see what all neat stuff can be accomplished with the new phone.. The basic questions I had are the following:
1) Is there a way to take MP3's off my computer and make them my ring tones, any software to do this ?
2) How do I watch TV and listen to satellite radio ?
3) I am having trouble entering my e-mail addy which includes a _ but I can not find out how to enter on my phone
4) I purchased a gig extra stick and I read somewhere about making that default for my e-mail and things of that sort but have had trouble getting this to work.
5) My ringer volume of the MP3 I put on it is real low and only plays the beginning of the song..
I greatly appreciate any assistance and thank you in advance.. Sorry if some of these are dumb questions, I just am clueless to this type of technology.
