We’re not familiar with the work of uSamp, a high-tech online research firm based in Los Angeles, but if the results of the survey (PDF) they released last week are accurate, Research in Motion (RIMM) is in trouble and the run on Google (GOOG) Android phones is about to hit a wall.

Drawing from a pool of 4.7 million panelists, uSamp asked a sample of 727 AT&T (T) and Verizon (VZ) smartphone owners how likely they were to switch to Verizon’s version of Apple’s (AAPL) iPhone next Thursday, Feb. 10, the first day it goes on sale.

The results are posted in full below the fold. The key findings:

• Among Android owners, 44% are either very likely (19%) or somewhat likely (25%) to buy an iPhone on Feb. 10.
• Among RIM owners, 66% are very likely (32%) or somewhat likely (34%) to switch on Day One.
• Nearly a quarter (24%) of the Android and RIM switchers say they’d be willing to stand in line to get one of the first Verizon iPhones.
• Owners of AT&T (T) iPhones are less likely to switch (8% very likely, 18% somewhat) but the switchers are more likely (29%) than RIM or Android owners to stand in line that first day. Perhaps they have more practice queuing up for an iPhone.
