You guys might want to look at this,

To the voda forums you go!

Look for this,

"The premium tier of our new price plans includes 1GB of data instead of 500MB.
If your current price plan has “YP” at the beginning of its code (see the first page of your bill) then you’re on the older version of the premium plans and are eligible to move to the new ones." ... FOR FREEE!

Now for my contract with my n900 started in feb/mar time and it starts with YP, so i suggest you guys go check it out.
