It happens on my 3 gmail accounts and only over wifi, I can receive with no problems but when I send, after many minutes, just says it can't find the smpt server and the message never leave the iPad. I have to open safari and use the web version for gmail. Same happens on my iPhone 4s. No problem over 3G.
I have tried in different networks, have deleted all the accounts and reinstalled, no luck so far. both iPad and iPhone are jail broken and running iOS 5.0.1
I searched the forum for similar issues but haven't found solution so far.
Any suggestion will be much appreciated.
