Deployed Devices
[edit | edit source]LGE
[edit | edit source]- LGE G7100
- User Agent declares it is MIDP 2.0; however it rejects MIDP2 Jad files
- By using Class.forName some MIDP2 classes can be seen to be present
- MIDP 2
- Pre-compiles Jars when they have been downloaded, so they are not stored in standard bytecode on the device
- This process can fail
- LG C1200
- LG C1500
- LG F2100
- LG F9100
Sendo
[edit | edit source]- Sendo M570 MIDP2
Siemens
[edit | edit source]- Siemens CL75 MIDP2
- Siemens ST60 MIDP1
Philips
[edit | edit source]- Philips Fisio 535 MIDP2
Conclusion
[edit | edit source]Esmertec Jbed lacks some fundamentals in the date implementation on HTC mobiles. Thus makes the implementation useless for most business applications. If this is due to bad hardware or Esmertec Jbed is still unknown.
