blackberry storm internet

I have blackberry storm/9530/ and use it for text,internet only.Verizon guys had a plan that did fit the bill;unlimited web;e-mail,text.Problem is that internet is slow/I got 5.0 O.S which is up to date/.Is there anything I can do to speed it up?I stopped by Verizon and asked how come my phone displays X1 by the signal symbol and am paying for 3G.They said that proccesor in BlackBerries is kind of slow and it's time to upgrade.Any other ideas?
