mobile web sites on 3

just noticed there is now an option on t'internet to view mobile web sites. upon clicking the more information icon i get the following message:

Bid on auction sites, read your e-mail, buy from your favourite retailers. Choose one of our great options to access the web on your mobile. Click on Get Access to expereince more!

then on the Get Access section it reads the following:

Daily free trial - 1hr 2mb
30 mins - max 0.5mb €0.30
1hr - max 2mb €1.00
1 day - max 4mb €2.00
1 week - 30mb €10.00

this is all new to me. does anyone know more about it. i know i could try and just play around with it but i'm just wondering if anyone else has and what they got? and what they thought/think of it?
