Blackberry 7520

I was thinking of moving to one but I like the use the AIM on my i730 quite a bit. I also use the internet to some degree but don't want to spend $50 a month on the blackberry service. Does anyone know if you can get basic internet on the blackberry?

I had a 7510 and to use the internet i just put my boost i730 sim card in it and it worked but I wouldnt know about the 7520...
