Query: Great phone

Great phone, but need to get used to the 'keyboard'. Phone has PDA functions which fits me. Reception is excellent in my area.One of the reasons for me to buy the phone was SMS, so I can communicate with friends/family in The Netherlands, that part is not working well. Sometimes I can send SMS sometimes not. People can reply and sometimes not at all. Very unreliable service from T-mobile ! Needs improvement, also depends on service contracts with other Telecom's. Sync with outlook works well, does what I need.Tip : You need to get the phone unlocked (via T-mobile) to use a sim card from foreign telecom provider.
