1. Flat rate data plans for all
(the UK and other markets have made a good start here)

2. Common framework for mobile page rendering and addressing (since I wrote this in December, I think m. is winning over .mobi, but we have a long way to go on page rendering)

3. Mobile location without GPS, but instead using zone detection (happening slowly – but read my guest post on msearchgroove to see how this is evolving)

4. Customer profiling (without this we’ll never reach the full potential of mobile advertising, and risk just flooding subscribers with the equivalent of junk mail)
