Ofcom's mobile broadband tests show O2 to be the fastest but location is the key factor for best results

O2 has launched an improved 3G service using the refarmed 2G mobile spectrum

More 3G spectrum available could cause problems at the UK's smallest 3G operator

3 will offer Nokia's E7 corporate smartphone in the spring, and has also introduced the Opera Mini browser

Mobile operator 3 is sending out people with MiFi hotspots in their pockets, to promote the idea of mobile broadband

The operator has confirmed it will offer Samsung's Galaxy Tab when it arrives, but has given no further details on pricing or launch date

Orange has been ordered by the Advertising Standards Authority to pull an advert which claimed it had a bigger 3G network than its rivals

Apple's iPhone 4 will be cheaper if you buy it from 3 - but check other details like delivery dates and network coverage

As the iPhone 4 arrives in UK shops, Tesco makes a tiny gesture, and shoppers hope that that 3 might undercut the other operators

Vodafone offers modem use of Apple's iPhone 4 for an extra fee. Only T-Mobile and 3 have still to declare prices
