ive decided on getting an o2 pay as you go dongle, for 15 quid a month to pay, and 3 gigabytes of data, with unlimited wi-fi. the trouble is, im not completly sure about what the 3 gigabytes of data is for, is it for downloads? or watching movies online,(i like to watch bbc iplayer) the main things im going to be doing is msn, facebook, youtube, some random browsing and free flash games such as miniclip and bbc iplayer, and some music downloads. could someone with more experience in dongles help me out here, ive got my mind set on the o2 dongle, and pay as you go, so please nothing like, "get vodaphone its better" etc. thanks
