Further notes on the internet packs
The activation took a few minutes when I bought the 10€ TIM microSim card at the International Airport of Rome (in November 2011). It was for 1 hour call and a very reasonable data limit for Internet (I did not reach the limit for my 5 days stay). You can buy more hours in the street (you could not add additional hours using their Internet service and your visa or paypal!). You are allowed to share the 3g connection (tethering is allowed) and use the wifi generated by your smartphone to connect your laptop to the Internet.

TIMxSMARTPHONE option in two flavors, one for blackberry and one for any other smartphone. You can activate it on any voice sim, 2€ per week 250MB of traffic. details here: http://www.tim.it/consumer/c56088/i56323/o104022/tariffa.do

TIMxSmartphone
2€ per week 250MB of traffic over quota will be 1€ for 40MB (not for iphone nor blackberry), after the first 40MB overquota (overquota is probably an outdated option) price is 0,05 € cents per KB (50cent per MB).
