Asawari,
Unfortunately, MapTips are not supported in ArcPad. While this could potentially work on a desktop computer (but has not been included in ArcPad), devices that run a Windows Mobile OS would not be able to utilize this technology. MapTips allow you to hover your mouse over a feature and return a text string. The Windows Mobile OS requires that you actually tap on the screen, it does not allow for "hover" capabilities.
My best suggestion would be to create a custom pointer tool which would automatically return either the entire attribute table or a message box containing the info from a few controls when a feature was selected by clicking on the map. This, however, would require that you have a background in vbscript or jscript.
