Changin To Linux!!!! (at last!)

I have installed many distros on my system such as SUSE 10, fedora core 5, vector linux, ubuntu 5.10. I have also tried some live distros such as knoppix, lindows etc... 1) i want to change to linux, but i want a distribution (or propably a package) so i can connect my mobile phone (sony ericsson k750i) to the internet (in most distributions the OS recognized my memory stick and i could transfer files, but none recognized the phone...what can i do for that??? 2) i was browsing the net and saw some videos on youtube about beryl...can i install it on any distro or only ubuntu?? i generally want something that is fully functional and does almost everything (i mean everything but cofee:P)! thank you guys!!! oh...not to forget! my setup is AMD Opteron Processor 858>>>2.01GHz and i have 512 Gigs of RAM my graphics card is nVidia GeForce 7100 GS 256MB i am actually a music producer who used to work on windows and now works on mac...but wants to load his PC with something else that is non microsoft!!! thanks guys!!
