GPRS is mighty expensive in the UK, just a month or two ago I looked into it on my T-Mobile pay-as-you-go plan and prices started at £1.50 per megabyte or £40 a month for 'unlimited' usage (discretionary 100MB cap, 12 month contract). This is way too much for me to use it for my regular email, let alone browsing the web.
So when I noticed this I thought, what a great idea!. A text-based web browser almost makes me want to sign up for GPRS so I could use the P800 as a mobile modem for the laptop. I'd still have to lug the laptop around along with the phone though. All I need now is a similar program for the Symbian OS.
