Approximately 80% of mobile phones on sale in the UK are web capable

"Here are the figures: over Ireland and UK operators there is a choice of more than 120 unique different handsets, for a total of nearly 280 choices.
Of this total:
82% are fully mobile web capable and should give a good user experience (like a Nokia 6300, Samsung E840, Sony-Ericsson W580i)
17% are capable but limited by screen size or poor software. (e.g. Sony-Ericsson W375, Nokia 3110)
1% are not capable, and anyway only available in pay-as-you-go and not targeted for web users. (e.g. Motorola W208, Nokia 1200) "
