[SyncEvolution] keeping in sync _two_ phones

Hi everyone. I'm trying to keep in sync two phones with my evolution, by using syncevolution. My phones are a Nokia E61 and a Nokia 6220 classic. Both are S60, but E61 is older than 6220. It happens to me quite often that after a sync I get data duplication, most often on the E61. The only way I found to get rid of such duplication would be to sync one-way from the server to the phone and then to re-sync immediately, again one-way, from the phone to the server. In such a way, the next two-way sync would work. But after such an adjustment, there will be very likely the same problem with the second phone, so to recover I will have to do the same with the second phone. And this will lead to problems with the first, and so on. In brief, the only way to keep all in order is to sync two-way one phone and one-way the other. Therefore I can never change my PIM data from the phone which I sync one way: such changes wuould be lost at the first sync. I'm not sure whether this is a regression: I do remember that everything looked fine before the last two versions of syncevolution, even though I had other problems (which are described in the wiki). Anyone has ever tested syncing with two different phones? Thank you very much Giancarlo
