One of the new features that was quietly sneaked into the latest release of JSMS is the ability to import from your GMail contact list. We use the official Google Data API to do this. It works very well because of this well defined API. This is very handy also if you travel a lot or use many PC's. Imagine you can have one central phone book (in GMail). Always use it to add / edit and delete new phone contacts, then when you sit down to use JSMS on any PC you can import your contacts knowing they are always up to date.
If you want to upload all your contacts from your phone to GMail, if you have a modern phone, you probably can.
With my Sony Ericsson W710i I can easily do this by
1. Go into my Sony Ericsson phonebook.
2. Go to Advanced settings
3. Click 'Backup phonebook to MS'.
4. Then use bluetooth (or use a data cable) to transfer the file PB_Backup.vcf from the System folder of your memory stick to your PC/Mac. 5. Then in you web browser, open Gmail contacts.
6. Click 'Import' at the bottom.
7. Select this PB_Backup.vcf file and Gmail should upload all your phone numbers (although sometimes Gmail upload doesn't work).
8. Open JSMS
9. Click 'Tools' -> 'Phone book...'
10. Click the 'Import' button.
11. Follow the steps for importing from GMail. Only Irish mobile numbers will be imported (and international numbers for O2 users).
Sorry I dont know about other phone models but take a look at your phone user guide to find out how you might do this for your particular make & model.
