I'm putting this out there to see how many other people are having a problem with the recent Skype update disconnecting when idle or not minimising meaning you can no longer receive incoming Skype calls. I sent this to three.co.uk support, lets see what I get back:
Dear Sir/Madam,
Since recently updating Skype on my ZTE F102 the application no longer remains connected in the background after I minimise it. The application also disconnects from Skype when it is idle. This now means I will no longer receive incoming *Skype* calls during this time. I notice your Support on the subject (under "Skype calls and chats") has Skype questions for "Making a call", "Sending a Skype Chat" and "Receiving a Skype Chat", but NONE for receiving Skype calls.
I politely request that you restore the original functionality of the Skype application for which I purchased my phone, by either a providing a new version or enabling me to revert Skype to an older revision.
Yours faithfully,
Benjamin Brown
