A slew of deals for internet-based software testing service DeviceAnywhere, benefiting from the booming interest in mobile applications from operators and device makers as they try to lure consumers. The WSJ.com reports on DeviceAnywhere’s partnership with RIM (NSDQ: RIMM) to let third party developers test their applications on a single system that represents 100 Blackberry models running on 16 networks. The company also announced it had launched virtual developer labs for British operators O2 and 3UK. Developers will be able to test their applications to ensure they work on any handset in the carrier’s portfolio, which in Three’s case means some 50 handsets, while O2 has over 40.
