T-Mobile’s introduction of the iPhone may have boosted Apple in in its U.S. race against Google’s Android mobile operating system, according to a new sales report from analysis firm Kantar Worldpanel.

The firm said Monday that the long-awaited addition of the iPhone to T-Mobile’s lineup gave Apple a 3.5 percent bump in the horse race, though it still only holds 41.9 percent of the U.S. market as compared to Android’s 51 percent. The figures are the result of over 240,000 interviews the firm conducted over a three-month period ending in May.

Microsoft’s Windows Phone platform picked up the third-place spot in the survey, with 4.6 percent of sales, about 0.9 percent more than the share Kantar determined that it had in the same period last year.

T-Mobile only added the iPhone 5 to its device lineup in April, six years after Apple introduced that smartphone.

While availability on the T-Mobile network gained Apple some ground, it didn’t appear to impact T-Mobile nearly as much. The company is still the fourth-largest carrier in the country with 10.1 percent of smartphone sales — a drop of 3.4 percent from the same period last year, the firm said.

The firm said that T-Mobile may, however, tick up in the next report when it has a full quarter of iPhone sales under its belt.

Not only did Kantar find that T-Mobile, as a carrier, seems to be best at attracting first-time smartphone buyers, it also found that 28 percent of all its subscribers who plan to upgrade their phone in the coming year expect to pick up an iPhone.
