Facebook Chat Jar For Nokia 2700 ((link))

You can. But web-based Facebook chat via Opera Mini on the Nokia 2700 is notoriously buggy. The browser constantly refreshes the page, drains the battery, and misses notifications. A dedicated JAR file runs in the background (multi-tasking is limited on S40, but many JARs can run minimized) and uses less data.

| Issue | Reason | |-------|--------| | No push notifications | J2ME doesn't support background TCP keepalive well; battery drain | | Disconnects every 5–10 mins | GPRS idle timeout, no background service | | No typing indicators | Protocol not supported by J2ME apps | | No file/photo sharing | MIDP 2.0 lacks advanced multimedia APIs | | Crashes if chat history > 50 messages | Heap memory ~1–2 MB per app | | SSL issues | Most J2ME apps didn't support TLS 1.0+; plain XMPP required | facebook chat jar for nokia 2700
