As everybody knows, NOKIA Phones since some generations have several (up to 5 in this case) sub-entries of different categories (Home, Work, Cell, Fax, Email, etc.) for each phone-book entry. Unfortunately this soft only transfers the first entry, ignores the other ones and does not assign the category.
After you read your data from your phone you need to explecitly export them or they are lost (a so called back-up does not contain any data!).
The other features are nice, may come handy for ppl. who like to send paid for SMS from the PC (even though there are plenty of free SMS Services online).
Conclusion: Make the soft transfer ALL entreis from the phone and also make it use the given categories. Cheers, S.
