trivia
This FCC approval document filed for the K3715 has an error on page 6 under 2.1.2, where it mentions the "Huawei E230". Presumably the document for the E230 was used as template for the K3715's approval, which may mean they are more or less identical. At least both share the same chipset (Qualcomm MSM6280).

I have unsoldered the antenna connection and taken the little antenna apart. I have seen that the antenna connects from only one point to the board. I expected to see a positive and a negative points where the little antenna is connected. But it is soldered only from one point to the board. How am I supposed to solder an external antenna to the board from one point. Antennas have two connections.

What do you think about installing e1820 firmware in to this device? would it increase its speed since e1820 supports speed up to 21.6mbps HSPA+? would this firmware make k3715 support HSPA+ high speeds?
