Orange UK has launched a unique connected plan which includes an iPhone 4 and iPad 2. This is aimed squarely at customers that want to get both an iPhone 4 and iPad 2 on contract but only receive one monthly bill.

Orange is offering any combination of iPhone 4 or iPad 2 on a single plan at a cost of £65.00 a month ($106). This includes 600 minutes of talk time, unlimited texts, unlimited BT Openzone WiFi access and a 2GB shared data allowance across both devices. The contract duration is two years.

A one off cost, in addition to the monthly plan is payable for the two devices. You can tailor the package to suit; if you want an iPhone 4 16GB or 32GB matched with an iPad 2 16GB, 32GB or 64GB. The only difference in cost is the one off payment. The cheapest combination of an iPhone 4 16GB and iPad 2 16 GB coming in at £99 ($162) and the maximum combination of a 32GB iPhone 4 and 64GB iPad 2 coming in at £299 ($488). All iPad 2 models are 3G and WiFi.

The offer is currently available to existing Orange customers. If you’re not an Orange customer, you can still get a similar deal; although the one off payment price increases by an additional £50 ($82)

Rogers in Canada has been offering something similar for a while; you pay an additional $30 and can share your 6GB of data between iPhone and iPad. However, it costs only a few dollars more to get an extra 5GB for iPad all on its own, so clearly this is still an area for experimentation.

Would you consider taking up an offer like this? Would you want AT&T or Verizon, or your local carrier to offer it?
