Mobile phone carrier AT&T is expected to soon add to its offering two new high-end Android-based smartphones, namely the HTC Incredible S and the Sony Ericsson Xperia arc.

Both of these handsets were spotted at the Federal Communication Commission not too long ago, with connectivity options that would make them fit for the operator's network.

The HTC Incredible S smartphone that emerged over at the FCC showed the model number PG32120, and included support for GSM 850, 1900 bands, along with 3G WCDMA bands II and V.

Basically, this would make the smartphone compatible with the GSM and WCDMA bands that AT&T uses in the United States, which suggests that it might not be too long before the operator launches this device on its airwaves.

As for the Sony Ericsson Xperia arc device that received the necessary approvals, it included quad-band GSM capabilities, along with support for WCDMA bands I, II, V and VI, which points at the same carrier as in HTC Incredible S' case.

As the guys over at Xperia blog note in a recent post, there are great chances that the smartphone would indeed arrive in the United States in the near future, and that AT&T would be the carrier to have it available on its network.

After all, the carrier already launched an Android smartphone from Sony Ericsson, namely the Xperia X10.

However, no official confirmation emerged for the time being, neither on the HTC Incredible S, nor on the Xperia arc being set to land at AT&T, and we should wait for a formal unveiling to be made before saying for sure that this would pan out.

In the meantime, we should note that the Incredible S was spotted at the WiFi Certification forum as well, and that the available documentation there pointed both at GSM and CDMA flavors of it headed for the market (via Wireless Goodness)

Verizon Wireless was previously said to carry the device in the US, and it remains to be seen what would the GSM version be all about. If not en route to AT&T, this device might be aimed at a Canadian carrier using the same bands as the US operator, Rogers.
