Can the 3G Hotspot on the Palm Pre carry a realtime skype video call without lags and stutters or do we have to upgrade to 4G?
it should work, but i suspect there will be lags/stutters. i know many video call apps would state that you should only use them with wifi or 4g, but they would still work on 3g. and considering i used to skype on my pc 10 years ago, with dial up, i would suspect 3g would be better than what i was working with....lol.
Simple answer: yes.
The iPhone 4S and 4 and many other devices support Skype over 3G.
However, 4G would allow for faster speeds, and as a result, better picture, less errors and freeze ups, and a better overall experience.
Also, I owned the Palm Pre+ with the hotspot feature, and yes, I was able to connect my MacBook to it and Skype a friend while on the interstate. Dont expect a flawless experience, but If the signal is strong, it will work.
