Just wondering, will this cause Lag on the tube? 

Can use our tube as 3G broadband modem?

as for tethering via WLAN, possible ! just enable Internet Connection Sharing from your pc notebook that is connected to Internet. then set your pc/notebook wifi as peer to peer so that your tube can connect to it. Once connected, tube can access internet via through pc/notebook connection. Details are pretty long but i'm sure you can find the exact instruction from the net

let me get you right .. you mean you want to Connect your pc to the internet via TUBE where TUBE got its internet connection from WLAN ??

if that is what you want, i've never done it before but it seems very limited option available

if TUBE can go internet via WLAN and your PC cannot WLAN maybe because no wifi card. So , the next option would be either bluetooth(if availabe) or usb cable. I've never came across a solution for this 2 option yet. Sorry, no help.

it is theme right? 

i want to install MFM 1.51. so which 1 i should go? Full customistion or original roads?

i just use Window Media Player and put the picture cover i want to the the album, on tube it shows the picture, but sometimes error happen such as some of the songs in the album didnt hav the pic or having other album picture, i also dunno y.... so some of them i just upload manually in the tube.

any1 can recommend a good way to upload the picture cover into the songs?

Oh thats ur question... well you know it is a touch screen phone after all. There is only 3 buttons, a camera button and the volume button. If wanna say put along the sides also i think the phone is out of space for the Play/Pause, Forward, Backward button u were saying..
