i am thinking about getting it, but before i do, i have a few questions

1. can you get a custom texting ringtone? right now i have the lg shine, and i can only pick out from 10 tones for my texting, that come with the phone


2. Can you text on the touchscreen without keyboard? if so, can you do it, while the phone is sideways


3. is it a good phone/worth buying?
oh, and if it's closed, can you make it go sideways?
