The appointment management of old Visors was to elaborate lengths and more convenient to use than the Nokia. I miss as the display soon overdue tasks. Also date repetitions are quite spartan. Something like "Every first Monday of the month" you will not find on the Nokia. The meherere years old Visor could.
The GPS can be described at best as moody. Wisely, the "Assisted GPS" (AGPS) is activated. For each GPS activation, the phone will contact a Nokia server to get current satellite data. It will always be about 5kB data transfer - probably the one who has a good data plan. Does not Want You the, so you can switch off the AGPS. Then take the locate between 5 minutes and several hours, despite a clear view of the sky and alleged 4 satellites in the status field of the mobile phone.
And I've already taken the mobile phone therefore to "repair" in the Nokia Store.
The e-mail program reported on a mailbox always "Memory full", even though no other programs running in the background. The problem was solved only moving the storage location for messages to E: instead of C :. You have to guess and only.
The rest of the applications works quite well.
Conclusion: In retrospect, I should have the XpressMusic 5800 bought - because the GPS works much more reliably, the Funktionsumfach is almost identical and it will cost only half.
