How to extract data and search in pcap format?

Hi friends I recently started research on pcap, how to capture network packets using mobile, I used the iphone(3g) for capturing the packets then I want to extract the packet and get some data, is that possible on the mobile. And also I want to store it in pcap format so I can extract those data on the server side.

My main motive for doing this research is to perform sniffing and searching for a specific data on the server side. Thanks. Capture packets over Wi-Fi and 3G. There are two ways to capture packets on a mobile phone: a Wi-Fi network card (for example, the TP-LINK WN725) or via 3G. Using a Wi-Fi card, you'll be able to record packets via WiFi or LAN; but with 3G, the phone has a 3G UMTS/HSPA modem which you would need to plug into a 3G dongle. If you don't have one of these devices, you will have to configure a 3G Wi-Fi hotspot on your phone. If not, you will have to capture a bit more.

Capture Packets using TCP/IP stacks. Using a Wi-Fi network card, you can easily use a sniffer such as Wireshark, which runs on Windows, Linux and Mac. Using sniffers such as Wireshark, you'll be able to record and analyze packets. Wireshark can be installed on most versions of Windows, Linux and Mac.

Using Wireshark, we first have to identify the target IP address on the phone's IP stack, for example. In the screenshot below, IP:192.168.103 indicates the IP address 192.103 of the device my phone is communicating to. You could identify a range of addresses on the phone by typing ip 192.
