We've been hearing rumors about Dell working on a Windows Phone 7 device, the Lightning, for a while now. During a recent earnings conference call, Dell CEO Michael Dell kept hopes alive that Dell hasn't given up on the Lightning.

Dell stated, "We're very much working with Android and Windows Mobile 7 and we see those platforms as more attractive alternatives to other suggestions that you may have offered."  The alternative he is referring to is likely the option for Dell to buy or develop their own OS.

It's rumored that Dell's Android phone is likely headed to AT&T later this summer and if the renderings do the Lightning any justice, it would be a nice addition to the Windows Phone 7 lineup this Fall.
