Update: The no-contract, Virgin Mobile iPhone 5 and promotional discounts are now live on RadioShack’s website.

We reported last week that the iPhone 5 would be coming to Virgin Mobile tomorrow starting at $549.99 on its usual no-contract, $30/month unlimited plans. RadioShack will be one of the first to carry the device and is also planning to offer a number of promotional discounts to celebrate the launch.

RadioShack will start carrying the Virgin Mobile iPhone 5 tomorrow both online and in-store for $549.99 (that’s for the 16GB model), but will also be offering $50 for eligible trade-ins until the end of next month. On top of the same $50 trade-in for iPhone 4S and iPhone 4, the retailer is also slashing prices on those two devices to $399.99 and $299.99 until July 6th.

Virgin Mobile will have both the black and white versions of the iPhone 5 available on its monthly no-contract plans starting at $35/month and its $30/month auto pay plan. 

RadioShack is also offering $150 off the iPhone 5 for AT&T, Sprint, and Verizon, which currently sells for $199 on contract,with an iPhone 4 or 4S trade in until July 13.

No word on if RadioShack will offer the $649.99 32GB model or the $749.99 64GB model through Virgin.
