gmail and gcal
Very sorry, yiplgwake, but I don't follow what you are saying. Surely you can't mean that you sent an email from your Touch without using a wifi connection? What would be the medium of transmission? Again, sorry if I misunderstand.
Sorry, I assumed you watched the video at the link, but here are the steps:
1. on your touch with wifi connection log into your gmail account
2. press the center plus button on the lower part of the screen
3. choose "add to home screen" button
4. use the name gmail, then hit the "add" button in upper right hand corner
5. repeat with gcal, tasks (visit google.com/tasks), docs, and maps
This creates a gmail button for your home screen. Now turn your wifi off so you are not connected to anything. Try a website in safari if you need to convince yourself. Then from your home screen hit the gmail button. Your gmail, as it was when you last connected to it with wifi, will show up. There you can label, archive, compose, etc. in gmail. This info will be saved and delivered to your gmail account next time you connect to wifi. I just did this again, but saved my composed email instead of sending it (I sent one yesterday and it worked). I reconnected my touch to wifi, hit the gmail button from my home screen and let it update. Then from my computer I went to gmail, went to drafts and sure enough, the draft was there. Works great!
Key is to remember to access gmail from your ipod when you do connect to wifi. It won't update gmail if you don't go to your gmail account on your ipod touch.
No need for MAIL or ical (which cannot be accessed when you are away from your computer or ipod touch/iphone) don't convert if you don't have to. Now if google would hurry and update the tasks feature to be displayed in google calendar on the desktop/ipod or iphone we would be set.
Any questions still?
