B2B software firm Sybase (Quote, Company Info) on Friday zeroed in on the wireless sector, announcing a $38 million all-cash deal to purchase Hayward, California-based AvantGo (Quote, Company Info) and fold it into the iAnywhere Solutions subsidiary.

As part of Sybase's iAnywhere, AvantGo will target wireless middleware for mobilizing Web content. More importantly, it lets Sybase expand its footprint in the B2B mobile market with the addition of AvantGo's offline Web capabilities and the popular premium MyAvantGo service.

The plan is to use AvantGo's software within iAnywhere to deliver an end-to-end m-Business platform that targets enterprise mobility of Web content, corporate data and applications. The acquisition is expected to close during the first quarter next year.

AvantGo, which has struggled to make money from its business and consumer focused mobile software, claims more than 7 million registered users for its content channel services but the bulk of its revenues come from licensing revenues for its AvantGo M-Business Server products, which are typically based on fixed-fee agreements.
