I've used MyPhoneExplorer before. I found it easy to use and don't recall encountering any problem as far as backing up contacts and SMS is concerned. I've read that Float's Mobile Agent offers 'more', but I can't find a place that summarises the advantage(s) it has over the MyPhoneExplorer in a nutshell. Could someone who has used both please explain the key differences between the two and share your opinion here?
